A=118degrees and
b is 5x-2
and d is 7x +4
OpenStudy (anonymous):
x=-3 ?
OpenStudy (anonymous):
nope 5 ,8 ,16 and 24 are my only options
OpenStudy (anonymous):
thanks though were you trying to get the same answer for both if so i did too
jhonyy9 (jhonyy9):
so because this is parallelogramm than we know that A=C and D=B
yes ?

oh yeah
OpenStudy (anonymous):
rightagaiin captain
jhonyy9 (jhonyy9):
A=118 so than C=118 total 118+118=236
yes ?
OpenStudy (anonymous):
the answer is 8 because ........
jhonyy9 (jhonyy9):
the sum of all angles degree is 360 degree ,right ?

360-236
OpenStudy (anonymous):
because its the closest i got to it being equal
OpenStudy (anonymous):
124 /2 or not
OpenStudy (anonymous):
how x cannot be -3?
when 5x-2=7x+4
OpenStudy (anonymous):
idk swalah just not an option

A+d as angles = 180
118+7x+4=180 solve this
jhonyy9 (jhonyy9):
than 5x-2=7x+4 because there we know that D=B,yes ?
OpenStudy (anonymous):
answer never will be 8
OpenStudy (anonymous):
ok swalah , and yes jhonny and red idk what i can multiply to get 58 i mean 7 x ? = 58
jhonyy9 (jhonyy9):
so 360-236=124 so from this result that D+B=124=5x-2+7x+4
yes ?

yes
OpenStudy (anonymous):
let me make sure if u mean that d is an angle so I am not just but I am completely sure
OpenStudy (anonymous):
the options i have never give me an equal
OpenStudy (anonymous):
u have 8
OpenStudy (anonymous):
8 is what i started of with only cus it was closest

and the angles will be like this b=38
d=60
jhonyy9 (jhonyy9):
so than 124=12x+2
122=12x
x=122/12 =61/6
OpenStudy (anonymous):
hmm doesnt make sense though does it

10.2???
